Answer:
I'd say x=4.5
Step-by-step explanation:
I learned this in 6th grade so don't completely take my word for it. But you can build off of my answer probably. Sorry.
Answer: 18
Step-by-step explanation:
18/2=9
18/3=6
18/6=3
18/9=2
18 is divisible by 2,3,6 and 9
Answer:
Natasha = 1 x 14 = 14
Peter = 2 x 14 = 28
Malachy = 1 x 14 = 14
Step-by-step explanation:
Ratio 1:1:2 so 1 + 1 + 2 = 4
Natasha, Peter and Malachy share of 56 : 56/4 = 14
Natasha = 1 x 14 = 14
Peter = 2 x 14 = 28
Malachy = 1 x 14 = 14
At first glance, it seems like a good estimate; big numbers make bigger number.
But, this is multiplication, which means big numbers will make an extraordinarily big number, in proportion to the numbers themselves.
If you round 31 3/4 up to 32, you can multiply that by 50. To make the estimate easier, multiply 50 by 2,
50 x 2 = 100
Take the zeros off 50 and 30 to make this a bit simpler, and multiply 5 by 3,
5 x 3 = 15
Add each of the zeros you took off to the 15 to make 1500 (1 zero was taken off 50, and 1 off of 30),
And then add 1500 to that other 100
1500 + 100 = 1600
A good estimate for 50 x 31 3/4 would be 1600, not 800.
Therefore,
No. Brenda's estimate of 800 is NOT a good estimate.
Answer:
71°
Step-by-step explanation:
All angles inside of a triangle add up to 180°, so you need to find angles that add up properly. First, you should subtract 38 from 180, which gives you 142°. Now, if you look at the outer measurements, you can clearly see that this triangle is isosceles, meaning it has both two congruent sides and angles. So we are left with 142, and it needs to be dispersed evenly into the two angles because they are congruent, so divide by 2 and you get 71° for X.
